Good point. Most of New England is just not that cold any more. Where I live in Northern New England, we got down to -20, almost -30 during that cold snap. And

Good point. Most of New England is just not that cold any more. Where I live in Northern New England, we got down to -20, almost -30 during that cold snap. And had a lot of sustained 0-ish temps throughout the winter. I wouldn't be comfortable using only a heat pump as a fuel source in my 1800s house. But I suspect it would likely keep the pipes from freezing. My relationship might not survive it, though. Better to keep the propane heat source for now :)
